COVER FOR STORAGE BATTERIES.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed November 9, 1917, Serial No. 201,158.

1 "0 all whom it may concern:

Be it known that I, WILLIAM MORRISON, a citizen of the United States residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Covers for Storage Batteries, of which the following is a specification.

My invention relates to covers for storage batteries. Heretofore these covers have been molded of hard rubber or like plastic material with a groove or depression about their edges which fit the inside wall of the hard rubber case, these grooves being filled with a sealing compound. In order to secure the cover to the case, screws or bolts are passed through the side of the case into the cover. My invention provides an adequate body of material to hold the screws, so that the cover is firmly held to the case.

In the drawings Figure l is a vertical cross section through the cover; and

Fig. 2 is a plan View of Fig. 1.

Referring to the drawings 1 is the main portion of the cover having a downwardly extending portion 2 and a peripheral flange 3, the edge of which fits the inner wall of the case 5. I mold integrally with the cover a series oflugs 4, each of which is long enough to extend to the inner wall of the casing. The lugs are conveniently formed by molding a block of the width of the lug at, as shown in Fig. 1, this block extending to the bottom of the cover; and then removing, as by sawing, the portion indicated by the numeral 5'. There is thus provided a continuous groove between the cover and the case, into which sealing material may be poured.

The screws 6 extend into the lugs 4:, which may if desired, be further extended as shown at 4, to afford additional strength.

I claim l. A battery cover comprising av main portion, a downwardly extending portion having a peripheral flange thereon, and a plurality of lugs extending from the downwardly extending portion, said lugs having their outer faces substantially in alinement with the periphery of the flange.

A battery cover comprising a main portion, a downwardly extending portion having a peripheral flange thereon, and a plurality of lugs extending from the downwardly extending portion, said lugs being spaced from the flange and having their outer faces substantially in alinement with the periphery of the flange.

3. A battery cover comprising a main por tion, a downwardly extending portion having a peripheral flange thereon, and a plurality of integrally formed lugs extending from the downwardly extending portion, said lugs being spaced from the flange and having their outer faces substantially in alinement with the periphery of the flange.

4. A battery cover comprising a main por tion, a downwardly extending portion having a peripheral flange thereon, and a plurality of 'lugs extending from the downwardly extending portion in both directions, said lugs being spaced from the flange and having their outer faces substantially in alinement with the periphery of the flange.

5. The combination with a cell case, of a battery cover having a mainportion, and a downwardly extending portion having a peripheral flange, lugs extending from the downwardly extending portion to the walls of the cell case, and screws extending through the wall of the case into the lugs.

6. The combination with a cell case, of.

a battery cover having a main portion, and a downwardly extending portion having a peripheral flange, lugs spaced from the flange and extending from the downwardly extending portion to the walls of the cell case. and screws extending through the wall of the case into the lugs.

In testimony whereof, I aflix my signature.

WILLIAM MORRISON.
